g++.

[Amir Hardon]

Hello all,
I wrote a program in C++, which is working great on my local
system(RedHat6.1).
Now, when I'm moving it to my employers server, I can't compile it,
g++ does not exist. Only gcc.
So I downloaded and installed the latest gcc version.
But still, the shell does not find g++.
What should I do?

I'm posting to the mailing list since it's very urgent.

Thanks allot,
    -Amir.

You didn't report what operating system your employer's server uses,
so it is hard to make a recommendation of what to do.

Start with making a detailed report of what exactly you did and how
exactly it failed. Perhaps you forgot to add the GCC target directory
(default is /usr/local/bin) to your PATH?

Martin

Martin thanks allot,
but David Pettersson already solve my problem(He didn't reply to the
list).
I fogot to do 'rehash'. What ever it is.

Thanks any way,

Best guess: it's swapping itself to death. Newer g++es have larger
memory requirements particularly when using the new, more compliant,
STL. Laptops tend to have less memory than anything else. In this case,
there's not a lot you can do other than fit more memory.

The other alternative is that there's an infinite loop somewhere in your
build of the GCC backend. Try building the equivalent C program, e.g.

    #include <stdio.h>
    int main() { printf("Hello.\n"); return 0; }

This shouldn't take more than a few seconds to build. If it does, try
building with -O1 or even -O0 optimization; if that works on the C then
it might help your C++ too.

Good luck. Please note that this question (and any follow-ups) would be
better suited to the gcc-help mailing list; this list is primarily for
gcc development.

I have installed G++ 3.1 on my laptop runing Debian Linux 2.2 and i 
tryed to compile simple aplication with it and it takes a very very long 
time!!! More than 20 minutes. What should I do?
i executed: g++-3.1 test.cpp

file test.cpp:

#include <iostream>
using namespace std;

int main()
{
    cout << "Hello.";
    cout << "\n";
    return 0;
}

Thanks for fast reply. Matis

  nunki[43]:~% as -V

...works fine for me. (If you have an older version, it's probably
time to install Sun's Recommended Patches for your system.)

http://gcc.gnu.org/install/configure.html should answer the first
part of this question.

[Tom Fetterer]

I have installed the g++ v3.0.3 compiler on a Sun ultra 5 running 
SunOS 5.8 and am having trouble convincing the assembler to use 
the assembly code produced. The errors I've been getting are like 
this:

/usr/ccs/bin/as: "/var/tmp/ccCJvg3c.s", line 1463: error: unknown 
opcode ".uleb128"


A couple of quick questions:

1. what version of "as" (the Sun assembler) does g++ expect?

2. is there a way of specifying the assembler that the compiler 
should call or what instruction set to use?

Any help would be greatly appreciated.

I need to load a binary of g++ on my Sun Ultra 5.

> uname -a
SunOS ckenn1 5.6 Generic_105181-05 sun4u sparc SUNW,Ultra-5_10  Ultra 5

I do not have a c compiler so the g++ source does me no good.  Please send
me the link to the ftp site where I
can get the binaries for g++.

Please don't send html.

Nope, not that we are aware of.  If you want help programming in C++,
comp.lang.c++ is a betetr place than here, if you think there is a
bug, just wrap it up, and submit a bug report.  It helps if you try
and verify that the behavior you see violates a requirement specified
in the language standard, or at least some book on C++.

Thanks, and happy hacking.

Dear Friends,
 
Can some tell me if the g++ has any bugs in binary 
output? I was trying some code with it (ASCII) and it doesn't seem to work 
properlly. The file keeps with 0 bytes in lenght.
 
I wouldn't like to report it as a bug "yet", since 
I'm not sure.
 
P.S.: I used the Debian GNU/Linux 2.1 with g++ 
2.91.60 (from within the .deb 2.1 package). I have just updated the system to 
Debian GNU/Linux 2.2 (and the latest gcc/g++) and I'll be testing it once 
again.
 
Anything,

Custodio, Leonardo.
